PowerTaq 2X PCR Mix with Dye V2 is an optimized premix designed for fast PCR amplification, with extension rates of up to 10 s/kb, helping to significantly reduce PCR reaction time. The reagent includes DNA polymerase, dNTPs, MgCl₂, KCl, and other stabilizers. Only primers and template DNA need to be added to perform amplification.
This product contains a loading buffer, allowing PCR products to be directly loaded onto agarose gels for electrophoresis without adding additional loading dye.
PowerTaq 2X PCR Mix with Dye V2 can amplify up to a 5 kb target fragment from complex genomic DNA or up to a 10 kb target fragment from simple templates such as lambda DNA. It is suitable for Colony PCR, genotype identification, vector construction, and other routine PCR applications.

Operation Description
Standard Protocol
It is recommended to prepare all reaction components on ice and then quickly transfer the reaction mixture to a thermocycler preheated to 98°C.

Note: The optimal reaction concentration varies depending on different DNA templates.
For a 50 µL reaction, the recommended DNA template amounts are provided separately.
For long-fragment amplification, the amount of template input can be appropriately increased.

Notes
* For high-complexity DNA templates (e.g., high GC content), extend the initial denaturation time to 3 minutes. For colony PCR, extend to 8 minutes to ensure complete denaturation.
** The annealing temperature can generally be set to 60°C by default.
For primers longer than 20 nt: use (lower primer Tm + 3°C)
For primers shorter than 20 nt: use the lower primer Tm
***
For low-complexity amplicons (e.g., plasmid DNA, lambda DNA) or fragments ≤1 kb: use 10 s/kb
For high-complexity amplicons or fragments >1 kb: increase extension time to 20–30 s/kb
